Japan plans to “compare notes” with the U.S. and other Group of 7 countries on risks posed by outbound investments, said Keiichi Ono, Japan’s senior deputy minister for foreign affairs. But Ono stopped short of saying Japan will implement new outbound screening measures, saying the country is still studying the restrictions.

Treasury Secretary Janet Yellen said she is “concerned” about China’s new export controls on critical minerals used to produce semiconductors (see 2307060053), saying the U.S. is still assessing the impact but that they “remind us of the importance of building resilient and diversified supply chains.” Speaking during a July 7 roundtable with American businesses in China, Yellen said the administration is working to make sure U.S. companies are competing with China on a “level playing field.”

Micron Techology is preparing for revenue losses caused by China’s recent sales restrictions on its products, saying in a recent Securities and Exchange Commission filing that Beijing “may prevent us from competing effectively with Chinese companies.” The U.S. semiconductor company said the restrictions are leading to “significant headwind” that “is impacting our outlook and slowing our recovery.”

Sixteen trade groups, including the U.S. Chamber of Commerce, the National Association of Manufacturers, PhRMA and BIO, asked U.S. Trade Representative Katherine Tai to press Mexico to comply with its USMCA commitments during her trip to Mexico for the Free Trade Commission meeting.

The U.S. “firmly” opposes export controls by China on certain metals used to produce semiconductors, a Commerce Department spokesperson said July 6. “These actions underscore the need to diversify supply chains,” the person said in an email. “The United States will engage with our allies and partners to address this and to build resilience in critical supply chains.”

As the U.S. continues to expand its chip export controls, South Korean and other multinational firms with semiconductor investments in China “face an uncertain future,” the Peterson Institute for International Economics said in a report this week. The report, authored by PIIE senior fellow Martin Chorzempa, outlines both the “collateral damage and new opportunities” for South Korean companies as a result of the Commerce Department's Oct. 7 controls (see 2210070049), saying Korean firms “have been some of the most impacted non-Chinese firms due to their large memory chip production facilities in China.” The report also recommends the U.S. do more to “reduce uncertainty” for allies operating in the region.

The Bureau of Industry and Security could use its existing “catch-all controls” to tighten restrictions around exports of sensitive artificial intelligence models, eliminating the need to develop new regulations to address emerging AI export risks, researchers with Georgetown University's Center for Security and Emerging Technology said this week. The researchers said the catch-all controls -- which allow BIS to restrict exports if there is “knowledge” the item will be used in certain dangerous ways -- may be “sufficient” to “address the use of AI in more traditional national security realms.”

China implemented export restrictions on gallium- and germanium-related items, which are used to make semiconductors and other key technology, the Chinese Ministry of Commerce announced, according to an unofficial translation. The restrictions will start Aug. 1 and are to protect China's national security, the ministry said. China is the top producer of the two metals, which are also used in solar panels, lasers and night-vision goggles. Gallium and germanium exporters will be required to apply for a license and report on their international buyers.

The U.S. is “overstretching the national security concept” and “abusing export control tools,” a spokesperson for China’s Foreign Ministry told reporters June 30, according to a transcript in English of the regular press conference where the comment was made. The spokesperson, asked about recent steps taken by the Netherlands to restrict exports of advanced semiconductor manufacturing equipment (see 2306300028) and potential future controls imposed by the Biden administration (see 2306290048), said the U.S. is “using all sorts of pretexts to cajole or coerce other countries into joining its technological blockade against China.” The country will “closely monitor relevant developments and firmly defend our lawful rights and interests.”
